SPECIFICATION forming part of Letters Patent 'No. 288,751, dated November 2?, 1853.

- Application filed June 19,1883. (No model.)

To all whomit may concern Be it known that I, FRANCIS RUDOLPH WOLFINGER, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Window-Sashes; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon.

Figure 1 'is an elevation of the inside of a window-frame, showing my improvement applied to the two sashes. Fig. 2 is a section, taken horizontally through Fig. l in the plane indicatedby the dotted line 00 ac thereon, showing the two sashes swung inward, the upper sash being depressed to its fullest extent and Fig. 3 is a perspeotive detail view of a sectional sash-stile with its dowel-pins. Fig. 4 is a perspective view of one of the hinged or pivoted sashes and its sectional stile.

The object of this invention is to afford easy access to the outside surfaces of glass in window-sashes for the purpose of cleaning the same; and the nature of my invention consists in certain novel improvements whereby I practically carry into effect the above object in a very simple manner, as will be fully un- I derstood from the following description,when

taken in connection with the annexed drawings.

Before particularly describing my improvements I will state that I may or may not hinge one side of each sash to a stile or upright slide;

but I prefer to do so for the reason that the sash will be connected to the windowframe, and can be readily swung inwardly for the purpose of cleaning the outer side of the glass. 1

A'designates a window-frame, which maybe constructed in the usual well-known manner, and which is preferably constructed with boxes toreceive weights and cords for balancing the sashes in the usual way.

B B designate the balancing weights; a a, the suspension cords, and b b the pulleys.

G G designate the frames of two windowsashes,each of which may be provided with one or more glasses. The meeting rails of these sashes are beveled in the usual manner, so that when they are brought together a close joint will be formed. Each sash-frame is preferably hinged on one side, as at d, to a stile, D, and when it is closed it is connected by dowel-pins c to another stile, D. The two stiles D D of each sash have attaohed to them the weightedcords a a, and

den hinges; or I may omit the hinges and sub-.

stitute pins or other suitable catches for unit ing the sashes to their stiles.

It will be observed that I have combined with a window-sash frame two stiles, D D, to which this frame is attached, so that free access is allowed to the outside of the glass for the purpose of cleaning it without the necessity of removing the window-strips or exposing a person to the danger of climbing on the outside of a window. It will also be observed that I provide a pin, for the purpose of connecting one side of each sash to its stile D. I also provide a high soffit, H, at the top of the frame A, inside thereof, for the purpose of allowing the inner sash to be raised high enough to swing the outer sash into the room when it is lowered to thebottom of the frame A.

One very essential feature of my improvement is the manner of rabbeting the sashframes to the stiles, and rigidly connecting the said frames and stiles by meansof the dowel -pins 0 and the key-pins 9, whereby there is no possibility of a casual displacement of the parts, and close joints are formed.-

Another important feature of my invention is theguide and retaining lips e e on stiles,

which are received in grooves made in the window-strips, thus, as above stated, keeping the stiles in their places in the window-frame.

It will be observed by reference to Fig that the vertical edges of the frames 0 are bev eled and fitso tightly that they keep out wind and water.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination of rabbeted stiles, a windowsash fitted thereto, the dowel-conneotions of the stiles and sash, and the retainingpins g, all constructed and adapted to operate substantially in the mannner and for the purposes described.

2. The combination of the rabbeted stiles D 1), having awindowsash attachedto them, the dowel-pins c c, the retaining-pin g, the lips e e, and the grooved strips F, all constructed and adapted to operate substantially in the manner and for the purposes described.

8. The combination of the soffit H, at the top of the frame A,With the window-sash, and the stiles D D, applied to the window-frame, substantially as and for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.

FRANCIS RUDOLPH WOLFINGER.
